The second monitor is no longer recognized

[bazarov]

I connected the DELL D6000 docking station with two monitors to my Mac, but suddenly the second monitor is no longer recognized.
I can see it in Display Link Manager, but not in the Mac settings.
I’ve tried restarting the system, updating Display Link Manager, and using new cables, but nothing works.
Sometimes (not always), the bottom monitor displays the screen as shown in the photos (sometimes in low resolution, other times in high resolution), but it isn’t recognized by the Mac, so I can’t work on that monitor (change the resolution, adjust the monitor layout, etc.).
Any suggestions?
MacBook Air M4 with Tahoe. I didn’t update to a new version of macOS before the problem occurred.






(It works perfectly on Windows)
